Science Buddies: Measuring Light Intensity Using the Inverse Square Law
You've probably heard that compact fluorescent light bulbs are more efficient than incandescent bulbs. More of the electricity they use goes into producing light, and less into producing heat than with incandescent bulbs. How much more...
Texas Instruments
Texas Instruments: Light at a Distance: Distance and Light Intensity
In this activity, students can use a light sensor to record the light intensity at various distances from a bulb. They will compare the data to an inverse square and a power law model.
University of Colorado
University of Colorado: Ph Et Interactive Simulations: Blackbody Spectrum
How does the blackbody spectrum of the sun compare to visible light? Learn about the blackbody spectrum of the sun, a light bulb, an oven, and the earth. Adjust the temperature to see the wavelength and intensity of the spectrum change....

Teach Engineering: Human Power
Students do work by lifting a known mass over a period of time. The mass and measured distance and time is used to calculate force, work, energy and power in metric units. The students' power is then compared to horse power and the power...

Serc: Investigating Electricity: Building Circuits in Elementary Science Class
In this exploration activity, learners compare the difference between series circuits and parallel circuits using wire, light bulbs, and D batteries.
Physics Classroom
The Physics Classroom: Electric Circuits: Circuit Builder
Students manipulate this virtual electronic circuit board where they can add resistors, light bulbs, wires, and ammeters to build a circuit, explore Ohm's law, and compare and contrast series, parallel, and combination circuits. Three...
National High Magnetic Field Laboratory
Magnet Academy: Fluorescent Lamp 1934
Compared to incandescent lamps, fluorescent lamps last longer, require less energy and produce less heat, advantages resulting from the different way in which they generate light.
